Appncauon mea April 2, 190s. serial No. 424,840.

To all whom may concern.'

Be it'known that I, JOHN A. MAnQUETTE, citizen of the United States,residing at -elfectually discharge any ashes collecting therein,and'which may be accurately adj usted to lit the desired fire pot.

`With this and other objects in view, that will more fully appear as thedescription proceeds, the invention consists in certain constructions,arrangements and combinations of the parts that I shall hereinafterfully describe and then point out the novel features thereof in theappended claim.

For a full understanding of the invention and the merits, thereof,reference is to be had tothe following description and accompany ingdrawing, in which:

Figure lis a top plan `View of my improved grate; F ig. 2 is atransverse section thereof; F ig. 3 is a detail view in section, of onevof the rocking bars; and, Fig. 4 is detail view in perspective, of aportion of one of the cross bars.

Corresponding and like parts are referred to in the followingdescription, and indie cated in all the views of the drawing, by thesame reference characters.

My improved grate embodies a plurality of longitudinally extending,transversely spaced grate bars l, the forward ends of which are upwardlydisposed to form "a front 2, the respective forward and rear eX-tremities of the grate bars being bolted or otherwise rigidly secured toa front cross bar 3, and a rear cross bar 4. The respective front andrear cross bars project upwardly and rearwardly beyond the Vextremitiesof the grate bars, as shown. The grate bars 1 are formed intermediate oftheir ends with transversely alining andpreferably circular openingsextending therethrough, and an actuating "rod 6 that is preferablysquare in cross section is journaled in these openings 5 with its endsprojecting outwardly beyond the grate bars l. A plurality of rockingbars 7 are mounted upon the actuating rod apparent that I have bottom ofthe grate, said G between the spaced grate bars 1, and are formed withpreferably square transverse openings 7a in which the actuating rod 6tits, and is securely held so that the rocking bars will turn therewith.These rocking bars are designed to be oscillated upon the operation ofthe actuating rod, so as to agitate the contents of the grate andelfectually discharge any ashes or thelike between the spaced grate bars1.

The front and rear cross bars 3 and l are formed at their ends withtransversely extending spaced channels 8, and are also formed intheir-respective projecting portions with longitudinal spaced grooves 9,which permit a side or end section of the grate to be broken 0E alongthe line of one of these grooves or channels and -to be readily detachedfrom the grate, as may be required, to cause the latter to fit a desiredlire pot. One of the projecting ends of the actuating rod 6 ispreferably formed with 4a' plurality of transversely extending spacedmarginal recesses 10, by means of which portions of the rod may bedetached to adjust the latter in length.

After the grate has been fitted to the lire pot, it is mounted thereinin the customary way, with the projecting ends of the actuating rodjournaled in the walls of the lire pot, and one of said ends extendingthrough said wall, and being designed to be engaged by a crank handle orsimilar implement, so as to shake the grate.

It will be noted that in case the grate is not of suiiicient width tofit the fire pot, one or more rocking bars 7 may be readily mounted uponthe projecting ends of the actuating rod, to increase the width of thegrate.

From the above description, in connection.

with the accompanying drawing, it will be provided a simple, durable andefficient construction of grate, which may be easily and cheaplymanufactured, and which consists of comparatively few parts that may bereadily assembled.

Having thus described the invention, what I claim is:

A grate of the character described, comprising a plurality oftransversely spaced L-shaped grate bars forming the front and grate barsbeing formed in the bottom with transversely alining circular openings,cross bars secured to the corresponding extremities of the grate barsand projecting therebeyond with their ends extending laterally beyondthe respective extreme grate bars, said cross bars being fornied intheir projecting portions With grooves extending longitudinally thereofand in their ends with transverse channels, an actuating rod square incross section loosely mounted in the circular openings in the gratebars, and rocking bars positioned between the spaced grate bars andformed with square openings in which the actuating rod fits, saidactuating rod having one of its ends projecting beyond the adjacentgrate bar and being formed in said end With circumferential recesses,all as and for the purpose specified.

In testimony whereof l alix rny signature in presence of tvvo Witnesses.i
